Electron pair dot structure in the case of ammonia is illustrated by the outer electrons surrounding the N atom. The Lewis point structure in the case of NH3 reveals that the N atom connects 1 pair of electrons with each of the three H atoms, resulting in a complete of three united pairs of electrons. The NH3 molecule adopts a three-sided pyramid-like shape due to the arrangement of the outer electrons according to its Lewis dot arrangement. In the Lewis symbol depiction of NH3, the N atom is enveloped by three points, each representing a pair of united electrons with a H atom.
